WILLIAM H. BROOKS', OE WEST POINT, NEW YORK.

STEAM-RADIATOR.

` SPECIFICATION forming part of Letters Patent No. 235,503, dated December 14, 1880.

Application filed July l5, 1880.

To all whom it may concern Be it known that I, WILLIAM H. BROOKS, of West Point, county of Orange, and'State of New York, have invented certain new and useful Improvements in Radiators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention has relation to that class of radiators which are commonly exposed in the room to be heated, and which are adapted for use in connection with high or low pressure steam, water, or other heat-conductin g uids, although these several features may he employed advantageously in radiators of Athe class called indirect radiators, or such as are not exposed in the room, but located iu an air-conducting flue.

Among the primary objects of my invention are the production of a radiator which, shall combine in one structure both the circulation of the heatconducting fluid and the simple expansion thereof without circulation, the utilization of the circulating caps or manifolds for forming the usual canopy or top upon the radiator, and to diminish the cost of manufacture, as well as to increase the heating capacity of the device.

To accomplish all of this the invention involves certain novel and useful combinations or arrangements of parts and peculiarities of construction, all of which will be hereinafter first fully described,and then pointed out in the claims.

ln the drawings, Figure 1 is an elevation and partial section of a radiator constructed' in accordance with my improvements.

having an'inlet, B, and an outlet, O. In t-he 5oA base I prefer to locate the trap D and the di- (No model.)

vision-plate E, both extending Wholly or nearly the length of the base, located between the discharging row of pipes and the row next adjacent, and operating, in a manner well understood, to separate the discharge from the inlet in order to insure a circulation 5 but instead' of this means of separating the two parts any equivalent Ineans of dividing them might be adopted, as will readily appear.

On the inlet side I locate the upright pipes F F, and on the outlet side the pipes G G, and connect the tops of each pair of these pipes by cap-pieces or manifolds H H, through all of which there is a circulation of the heatconveying duid from inlet to outlet.

The pipes Fand G are cut to equal lengths, and each screw is threaded at top and bottom with alternating right and left hand threads or windings, so thatI all the parts may be attached, in the usual manner, by simply turning the pipes in the seats provided for them, and so thatthe caps may be brought to one level'.

Between the outer rows of tubes I locate simple stand-pipes K K, of any approved pattern. These are closed at top and simply admit the steam or heating-fluid by expansion without circulation. The tops of these lastnamed pipes fall below the level, and out of the way of the under sides of the caps H, and they are screwed into the base before the caps are finally located. The caps or manifolds H are preferably cast, a channel being formed on their under sides-for the cross-passage of steam, Sac. The upperI faces of the caps are plain or .practically smooth, and the edges thereof are formed so that one will abut against the other. All being brought to the same level by suitable adjustments of the tubes F and G, they together form the top of the radiator, and thus dispense with the additional top or canopy usually made separable from the other parts, and almost always employed upon direct radiators to form a table or stand. The edges of the caps exterior to the cross-passage may be perforated after any design, and thus allow the rising heated air to pass out from between the. heatin g-pipes.

The ends of the caps and the outer edges of the two exterior pieces may be provided with IOO a narrow depending Hanne, itI desired, to conceal the upper parts of the tubes or their connections.

A radiator thus constructed insures the circulation through it of a considerable portion of the steam, tvc., and it also ati'ords the simple expansion into the inner tubes, the degree of which will be regulated automatically h v the degree of back-pressure, and may be held under control b v the application of cocks or valves to the inlet and discharge pipes in the ordinary way. Thus all the advantages of both classes of radiators are combined in the one structure, and the economic and best pos sible utilization of the heat is insured. The circulating steam being brought in close proxiinity to the cap-plate (through the channel of which this cap-plate forms the top) brings the plate to a higher degree of heat than a separate plate could he brought, and thus better heats the impinging,r air. The heated air rising between the expansion-tubes is further heated by contact with the more higgi'hly` heated upper plates before escapin; r into thc room. rlhus, While the improved radiator is produced with a top or canopy, this top is heated b v direct contact with the live steam upon its undersurface, and not by heated air, as in the case of the ordinary' separable tops, ati'ording thereby an increased advantage in the matter of heating the room or apartment.

The number of tubes ot' either class to be employed is, of course, immaterial, any number being applied. accordingr to the size oi' radiator, or according to the'circumstances of the particular case.

The style of expansion-tubes is also iinina.- terial. Plain tubes are represented in the drawings for convenience ot illustration; but any other styles may be adopted.

When constructed substantially in accordance with the foregoing explanation, the iinproved radiator will be found to admirably answer the several purposes and objects of the invention, as previously stated.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In combination with a radiator-base in which the discharge is separated from the inlet by a suitable divisionplate,a series of tubes communicating with said baseindependeiitlyof the circulating-pipes, said tubes being closed at top and adapted to admit the heating-Huid by expansion, substantially as and for the purposes set forth.

2. The herein-described cap or manifold, adapted to connect the opposite inlet and outlet pipes, said manifolds consisting of aat or plain top, a suhjacent uidchannel formed therein, and means for connecting the channel with the pipes, the top being made to extend beyond the tiuid-channel,and being,r perforated upon each side thereof, for the upward passage of heated air, substantially as shown and described.

3. In combination with circulating-pipes F (i, the manifolds H and expausioii-tubes K, the edges of the manifolds being perforated to permit the heated air to rise freely, substantially as shown and described.

4. The herein-described radiator, composed of base A, having inlet and outlet B and C, trap l) E, circulating-pipes F and G, manifolds H, and expansion-tubes K, all constructed and arranged to operate substantially in the manner and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.
